Question

Would this work? function flattenAsync(asyncIterable) { const asyncIterator = asyncIterable[Symbol.asyncIterator]();

const next = (a) => Promise.all([a, asyncIterator.next()])
.then(concat);
const concat = ([a, {value, done}]) => {
if (done) return a;
a.push(value);
return next(a);
};
return Promise.resolve([]).then(next);
}
